brake fluid AUDI S3 2012 User Guide

@ For the sake of the environment
Because of the problem of proper disposal
of brake fluid as we ll as the special tools
req uired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
All work on the battery requires technical
knowledge!
F ig . 1 64 Eng ine co mpa rtment: Batte ry w it h cover*
The battery is located in the engine compart­
ment
c::> fig. 164 and is near ly m ain te nance­
fre e.
The condition of the battery is checked in the
framework of the inspection.
Disconnecting the battery
The batte ry should not be disconnected. Some
ve hicl e functions such as power windows are
unavailable if the battery termina ls are dis­
connected. These funct ions have to be re­
l earned after the battery term inals are con­
nected aga in. To prevent this, the battery
should only be disconnected from the vehicle
electrical system if absolutely necessary .

Vehicl es not driven for long periods and
sho rt -d is tance op eration
If you do no t drive your vehicle for several
days or weeks, electrical consumers are grad ­
u ally scaled back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time
c::, page 167. Some convenience functions
such as opening w it h the remote control key
may not be available. These conve nience func­
tions wi ll be available again once you switch
the ignit io n on and sta rt the engine. Even
whe n consume rs a re switched off, the battery
will become deeply discharged by stand -by
power consumers if the vehicle is not driven
for several months . Deep discharging results
in a chemical reaction that destroys the inside
of the battery. The battery must be charged
every month to prevent th is
c::, page 209. Do
not disconnect the battery or the anti-t heft
alarm system* will not work .
Winter operation
Cold weather places higher demands on the
battery. This results in reduced starting abili­
ty. Have the battery checked and recharged if
necessary befo re the cold weather begins.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::, page 209 . A well
c harged bat tery will not o nly prevent s tarti ng
problems when the weather is cold, but will
also last longer .

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces­
sive tire wea r, impair ing t he safety of the veh i­
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Ve hicles w it h quattro ® must always have t ires
of the same s ize, construction and tread type.

A WARNING
Sudden tire failure can lead to loss of con­
tro l, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency and then with special care and at lower
speeds .
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle con trol.

New tires and replacing tires and wheels
